Resumen:
Cinnamon (Cinnamomum sp.) is a species with few but significant health
limitations, of which Phytophthora cinnamomi and Fusarium sp. are the
most important ones that affect the root. Their control based on
synthetic fungicides has favored resistance due to poor handling, so
their control with essential oils is a viable alternative. The objective
of this study is to determine the antifungal potential of thyme and
clove - essential oils for the control of P. cinnamomi and Fusarium sp.
isolated from Cinnamomum verum. Concentrations of 60, 120 and 300 mu L
L-1 were evaluated for both oils and phytopathogens. Data recorded on
the mycelial growth rate of pathogens after incubation of Fusarium sp.
at 25 +/- 1 degrees C and 28 +/- 1 degrees C had a significant
difference in the concentrations tested. When clove essential oil was
used in P. cinnamomi, the pathogen did not grow with the concentration
of 300 mu L L-1; with 120 mu L L-1 growth rate was 0.06 mm per day, and
with the concentration of 60 mu L L-1, it reached a growth rate of 1.16
mm per day. With respect to Fusarium sp. mycelial growth was completely
inhibited with doses of 120 and 300 mu L L-1 of essential oils; with
thyme oil a similar trend was observed at concentrations of 120 and 300
mu L L-1 greatly inhibiting effects of the two pathogens. It is
noteworthy that the doses of 300 mu L L-1 of the two essential oils are
able to inhibit in their entirety (P <= 0.05) growth of both pathogens.
The use of thyme and clove essential oils can be an alternative in
preventive control of cinnamon root diseases.
